Ben Lecomte, who has previously swum across the Atlantic Ocean in 1998, left the shores of Choshi in Japan on Tuesday morning, heading east.
The 50-year-old plans to swim from Japan to San Francisco in 180 days, covering 8,000km. His journey will take him through 1,600km of the garbage patch, in an attempt to raise awareness about plastic pollution. The Great Pacific garbage patch, according to the latest March estimate, is twice the size of France and contains nearly 80,000 tonnes of plastic.
Also known as the Pacific trash vortex, the patch is caused by the North Pacific gyre – a circle of currents that keep plastic, waste and other pollution trapped.
According to scientists, the patch has been growing “exponentially” in recent years. The March estimate found it was 16 times larger than previously expected.
Lecomte and his support team intend to sample the water they swim through every day of the journey, and gauge the level of plastic and microplastic pollution.
The expedition’s first mate, Tyral Dalitz, told the ABC the team wanted to dispel a myth about the garbage patch.
Rather than being made up of large pieces of plastic, most of the pollution is made up of invisible pieces of microplastic that sit in the water like a “plastic smog”, he said.
“In reality the truth is much worse – the ocean is now filled with microplastics ... Rather than calling it an island of trash, it is more like plastic smog throughout the ocean.”
